Dental Lasers: Innovation and Advancement in Dentistry

The technological revolution has increased the availability of information and the popularity of Light Modification by Stimulated Emission of Radiation, thereby improving patient prospects for painless and "non-invasive" procedures. In the field of dentistry, lasers have created a potentially lucrative market for patient care and well-being. The introduction of lasers into dentistry liberated dentists from the limitations of conventional procedures. Recently, the introduction of lasers into contemporary dentistry has afforded both clinicians and patients convenience, efficacy, specificity, and comfort. In the past, lasers were only handled by specialists; however, laser advancements have revealed a paradigm shift in dentistry, indicating a promising future for all aspects of dentistry and postsurgical care.

Advancement in Laser Dentistry

Diode lasers are primarily utilised in soft tissue surgeries and bleaching-like cosmetic dental procedures. The diode laser has emerged as a portable, inexpensive, and user-friendly instrument for soft tissue surgery. It provides advantages comparable to precision in cutting gum tissues, bloodless surgery, and minimal swelling, scarring, and pain prior to and after surgery. Additionally, the laser can absorb intracellular water from pathogens.

Laser types

The diode laser (810nm – 980nm), CO2 (carbon dioxide, 10600nm), and the YAG family (2100nm – 2940nm), i.e. ErYAG (erbium yttrium aluminium garnet), ErCrYSGG (erbium chromium yttrium selenium gallium garnet), and HolYAG, are the primary lasers used in dentistry (holmium yttrium aluminium garnet). These are typically considered lasers for hard tissue. NdYAG (neodymium, yttrium aluminium garnet) is an effective dental laser wavelength for soft tissue procedures, but many of the units on the British market do not point consistently.

These lasing media emit light with a specific wavelength that is widely absorbed by certain tissues. YAG lasers have an absorption peak in water; consequently, the water component of tissues is evaporated prior to structure breakdown. Diode and NdYAG lasers have an absorption peak in pigmented tissue, making them suitable for lasering and coagulating periodontal tissue. The operator can vary the laser's periphery on the target tissue and control the energy applied to the optic resonator. In addition to controlling pulsing or nonstop lasing, pulse duration and pulse relaxation times, the specialist can also control pulsing or nonstop lasing. This combination will control the effects on the target tissue.

Presentation and use

Depending on the type of laser, the laser's technology is housed in sleek and ultramodern-appearing holders with parameter setting buttons or LEDs and a delivery arm that may be articulated, flexible, or an optical fibre. In general, YAG lasers are recommended for cavity medication and hard tissue removal, while diode CO2 and NdYAG lasers are useful for soft tissue procedures. Hard tissue lasers have handpieces that simulate the familiar dental turbine sensation.

Emotion management

When healthcare professionals report failed analgesia cases, the emotional response to pain takes precedence. Memory can exacerbate pain perception; therefore, it is essential for the physician to 'condition' the case with a sympathetic attitude. This may involve using euphemistic phrases such as "you will feel some light pecking" instead of emotive and untrue phrases such as "you will feel no pain." The limbic-hypothalamic system filters stimuli, while the frontal cortex influences the rational interpretation and response to pain. Individuals with a strong memory of painful experiences at the dentist will interpret this as physical pain despite the fact that it is a minimally painful activity.

Opportunities of Lasers in Dentistry

Several decades of development have resulted in a highly developed state of laser technology for hard tissue applications and soft tissue surgery; however, further advancements are still possible. Particularly for targeting specific cells, pathogens, or molecules, the field of laser-based photochemical reactions holds great promise for additional applications. Combining diagnostic and therapeutic laser techniques is anticipated to be an additional area of future growth. In the next decade, it is anticipated that specific laser technologies will become indispensable components of modern dental practice.

In recent years, such costly cosmetic dentistry procedures, including dental lasers, have been in high demand due to the high purchasing power of the populations of both developed and developing nations. Increasing elderly populations and edentulous cases are major factors driving the global market for dental lasers. 20% to 80% of the global geriatric population and 60% to 80% of the geriatric population have immediate dental treatment needs. The global market for dental lasers is anticipated to expand in the coming years due to the rising prevalence of dental diseases such as bleeding gums and untreated tooth decay. It is estimated that approximately 47% of adults over the age of 30 are affected by at least one form of periodontal disease, while approximately 35% of adults over the age of 60 are toothless.
